IQ Cockpit fails to start

[kimon_moschandreou]

After several days IQ Cockpit froze, it was stopped normally and now it fails to start with the messages below. Also in the same installation SCC is not running, it only starts the agent, not the web app. Any ideas?

asiq bin $ cockpit.sh

The resolution was to empty the COCKPIT-4/services/Messaging/activemq-data directory. Then cockpit started fine. It seems that when it needs more disk space for the MQ messages the whole application crashes..

I hope this will help somebody else
